Intraductal papillary neoplasms of the bile ducts: a comparative study of a rare disease in Europe and Nagoya, Japan.

BACKGROUND: Intraductal papillary neoplasm of the bile ducts (IPNB) is a rare disease in Western countries. The aim of this study was to compare tumor characteristics, management strategies, and outcomes between Western and Eastern patients who underwent surgical resection for IPNB. METHODS: A multi-institutional retrospective series of patients with IPNB undergoing surgery between January 2010 and December 2020 was gathered under the auspices of the European-African Hepato-Pancreato-Biliary Association (E-AHPBA), and at Nagoya University Hospital, Japan. RESULTS: A total of 85 patients (51% male; median age 66 years) from 28 E-AHPBA centers were compared to 91 patients (64% male; median age 71 years) from Nagoya. Patients in Europe had more multiple lesions (23% vs 2%, P < .001), less invasive carcinoma (42% vs 85%, P < .001), and more intrahepatic tumors (52% vs 24%, P < .001) than in Nagoya. Patients in Europe experienced less 90-day grade >3 Clavien-Dindo complications (33% vs 68%, P < .001), but higher 90-day mortality rate (7.0% vs 0%, P = .03). R0 resections (81% vs 82%) were similar. Overall survival, excluding 90-day postoperative deaths, was similar in both regions. DISCUSSION: Despite performing more extensive resections, the low perioperative mortality rate observed in Nagoya was probably influenced by a combination of patient-, tumor-, and surgery-related factors.

Repeated pancreatic resection for pancreatic metastases from renal cell Carcinoma: A Spanish multicenter study (PANMEKID).

BACKGROUND AND OBJECTIVES: Recurrent isolated pancreatic metastasis from Renal Cell Carcinoma (RCC) after pancreatic resection is rare. The purpose of our study is to describe a series of cases of relapse of pancreatic metastasis from renal cancer in the pancreatic remnant and its surgical treatment with a repeated pancreatic resection, and to analyse the results of both overall and disease-free survival. METHODS: Multicenter retrospective study of patients undergoing pancreatic resection for RCC pancreatic metastases, from January 2010 to May 2020. Patients were grouped into two groups depending on whether they received a single pancreatic resection (SPS) or iterative pancreatic resection. Data on short and long-term outcome after pancreatic resection were collected. RESULTS: The study included 131 pancreatic resections performed in 116 patients. Thus, iterative pancreatic surgery (IPS) was performed in 15 patients. The mean length of time between the first pancreatic surgery and the second was 48.9 months (95 % CI: 22.2-56.9). There were no differences in the rate of postoperative complications. The DFS rates at 1, 3 and 5 years were 86 %, 78 % and 78 % vs 75 %, 50 % and 37 % in the IPS and SPS group respectively (p = 0.179). OS rates at 1, 3, 5 and 7 years were 100 %, 100 %, 100 % and 75 % in the IPS group vs 95 %, 85 %, 80 % and 68 % in the SPS group (p = 0.895). CONCLUSION: Repeated pancreatic resection in case of relapse of pancreatic metastasis of RCC in the pancreatic remnant is justified, since it achieves OS results similar to those obtained after the first resection.

Rotura espontánea de bazo en paciente tratado con acenocumarol / Spontaneous rupture of spleen in a patient treated with acenocoumarol

Aunque la causa más frecuente de rotura esplénica es la traumática, podemos encontrar roturas sin relación a un traumatismo previo. Se está objetivando un aumento de roturas espontáneas en relación con tratamiento anticoagulante. Presentamos el caso de un hombre en tratamiento con acenocumarol que presentó una rotura espontánea esplénica que requirió esplenectomía urgente. La rotura de bazo es una entidad grave que debe considerarse ante todo paciente con un abdomen agudo. Aunque las causas más frecuentes de rotura esplénica atraumática son las complicaciones neoplásicas e infecciosas, se han objetivado varios casos asociados a terapias antiagregantes y anticoagulantes. Dado el aumento de población que precisa anticoagulación oral, la sobredosificación con acenocumarol debe considerarse como una posible causa de rotura esplénica. Debemos sospechar esta entidad ante todo paciente en tratamiento con anticoagulación oral con un abdomen agudo.

The splenic rupture is most commonly related to trauma, but spontaneus ruptures have also been described with increasing frequency. We present a case of a male patient with spontaneous splenic rupture due to oral anticoagulant overdose that required urgent splenectomy. The spontaneous splenic rupture is a life-threatening condition that must be considered in patients with acute abdomen. Although most ruptures are associated with to neoplastic and infectious complications , recent reports have related rupture with anticoagulant and antiaggregant therapies. Moreover, since the number of patients undergoing oral anticoagulant therapies is growing, overdose of anticoagulant drugs must be considered as a possible ethiology of spontaneous splenic rupture and suspect this association in patient with acute abdomen undergoing anticoagulant therapy.

Intususcepción ileocólica en el adulto como presentación de un linfoma no Hodgkin de intestino delgado / Ileocolic Intussusception in Adults due to Small-Bowel Non-Hodgkin's Lymphoma

La intususcepción intestinal, definida como la penetración de un segmento intestinal en otro adyacente, es una causa infrecuente de obstrucción intestinal en el adulto. El objetivo de este trabajo es presentar el caso de un paciente adulto con intususcepción ileocólica como presentación de un linfoma no Hodgkin de intestino delgado. Este paciente presenta una causa poco frecuente de intususcepción intestinal. Dada lo inespecífico de la clínica, el diagnóstico etiológico suele ser intraoperatorio, precisando resección de la lesión causante y, en el caso de nuestro paciente, quimioterapia adyuvante(AU)

Intestinal intussusception, defined as penetration of an intestinal segment into an adjacent, is a rare cause of intestinal obstruction in adults. The aim of this paper is to present the case of an adult patient with ileocolic intussusception as presenting a non-Hodgkin lymphoma of the small intestine. This patient has a rare cause of intestinal intussusception. Because of its non-specific clinical, etiologic diagnosis is usually intraoperative, requiring resection of the culprit lesion and, in the case of our patient, adjuvant chemotherapy(AU)
